I am not able to reproduce your problem. Are you able to save using other browsers on the same system such as Firefox or Chrome?
Will you be able to attach a screen shot showing the issue?
Thanks Lucia - This problem was reported to me by a client. When I tried it on one of my computers, I got the same result - the 'Exporting ...' progress bar continued to display indefinitely (I left it on one occasion for 20 minutes with no progress)
However, when I tried it again today, it worked perfectly - I reported this to my client and he too successfully exported to a PDF.
I can only assume that this was a temporary glitch on one of your servers, and the problem is now resolved.
So thanks again, and you can now close this incident.
I am glad that things are working now.
Yes, it was most likely a momentarily glitch at that time.
